I'm having a problem with my wifi in my house when my Xbox One is connected to my Modem/router via cable. When anyone is on their tablet/phones their wifi quits working. You shut off the Xbox One or unplug the ethernet cable and everyone's wifi works with no problems. If you have the Xbox One connect via wifi there are NO problems. The only problem with that is the download speed is about 1/5th the speed. I'm just curious if anyone has had this problem.
